Reflecting button for signs



June 21, 1932. T. R. WILLWERSCHEID REFLECTING BUTTON FOR SIGNS Filed Aug. 26, 1929 iNVENTOR I head 0 r R Wllu/PrJc/ze id ORNEY Patented June 21, 1932 THEODOR R. WILLWERSCHEID, OF CLEVELAND, OH IO BEFLECTING BUTTON FOR SIGNS Application filed August 26, 1929. Serial No. 388,451.

the use of such housing and embody the reflecting surface within the button itself.

1- This'and other features of my invention will be more specifically set forth in the following description and the accompanying drawing, wherein:

Figure 1 is a partial view of the face plate of a sign with my improved button positioned within an opening in said plate; and

Figure 2 is a section on line 22 of Figure 1.

In carrying out my invention in the form 25 illustrated, I embed within the bottom of the button 2 a reflecting plate 3, the reflecting plate 3 being properly curved in relation to the curved outer face 4 of the button to deflect the rays of entering light at the desired 1 and proper angles. This reflecting plate 3 may be of any suitable reflecting material, and preferabl is enough narrower than the width of the button so as to reflect all rays out through the projecting face of the button and prevent any of those reflected rays striking the side walls of the button holder.

In the drawing, I show a preferred form of holder for this button, consisting of a split metal ring 5, having an exterior groove 6 in its outer edge to receive the edge of the sign plate A. The bottom 7 of the ring is bent inwardly under the button to hold the buttons clamped in position.

In the form shown, the button is formed with a shoulder 8 which will contact with the portion of the ring formin the groove 6, so that the button is clamped etween said flanged portion 6 and the bottom of the ring.

By having the reflecting surface apart of the button itself, instead of part of an enclosing housing, I am able to protect the. reflecting surface against damage through being exposed, and am able to position it in anydesired relationship to the face of the button, and to save the ex ense and inconvenas ience of an enclosing re ector housing. I

By means of the construction shown, I not only savethe expense of a special housing for the glass button, but am enabled to position the reflecting plate 3 at any desired distance i from, and in any desired relation to the exposed surface of the button, and, am thus enabled to regulate the angles of refraction, as desired.

I do not, however, restrict myself to this i particular form of holding the button in position, nor to the articular shape or form of button shown, t e scope of my invention being set forth in the accompanying claims.

I claim:

1. A light reflecting unit, comprising a one-piece glass button, a reflecting unit 1mbedded within said button in opposition to the exposed face of the button and spaced from the rear end of the button. A

2. A light reflecting unit, comprising a solid, one-piece glass button having acurved face, an oppositely curved reflecting unit imbedded in said button in opposition to the curved face of the button, and spaced from the rear end of the button.

In testimony whereof I aifix my signature.

THEODOR R. WILLWERSCHEID.
